axios请求requestBody和formData

前言

在vue的后台管理开发中,应需求,需要对信息做一个校验,需要将参数传递两份过去,一份防止在body中,一份防止在formdata中,axios请求会默认将参数放在formdata中进行发送。
对前端而言其实都一样,无非就是参数的格式问题。
对后端而言
(form data)可以用request.getParameter(接收参数名)
(request payload)用request.getParameter是接收不到值,必须用输入流获取,得到字符串在转json
应需求有的接口是需要放在body中有的要放在formdata中,所以前端需要做一个灵活的处理,因为就算只是更改headers中的字段也会让人时时刻刻记得。所以最终我将请求文件封装如下:
/**

import axios                from ‘axios‘
import { Message} from ‘element-ui‘
import router               from ‘../router/permission‘
import Vue from ‘vue‘
import VueCookies from ‘vue-cookies‘
const moment = require(‘moment‘);
const Base64 = require(‘js-base64‘).Base64;

// loading框设置局部刷新,且所有请求完成后关闭loading框
var loading;
function startLoading() {
  loading = Vue.prototype.$loading({
    lock: true,
    text: "Loading...",
    target: document.querySelector(‘.loading-area‘)//设置加载动画区域
  });
}
function endLoading() {
  loading.close();
}

// 声明一个对象用于存储请求个数
var needLoadingRequestCount = 0;
function showFullScreenLoading() {
  if (needLoadingRequestCount === 0) {
    startLoading();
  }
  needLoadingRequestCount++;
};
function tryHideFullScreenLoading() {
  if (needLoadingRequestCount <= 0) return;
    needLoadingRequestCount--;
  if (needLoadingRequestCount === 0) {
    endLoading();
  }
};
// 请求拦截
axios.interceptors.request.use(config => {
  let token = "";
  showFullScreenLoading();
  if(VueCookies.isKey(‘userinfo‘)) { 
    const USERINFO = VueCookies.get(‘userinfo‘);
    if(config.method == ‘get‘) {
      token = Base64.encode(USERINFO.token + ‘|‘ + moment().utc().format(‘YYY-MM-DD HH:mm:ss‘ + ‘|‘ + JSON.stringify(config.params)));
      config.params.hospitalId = USERINFO.hospitalId;
    } else {
      token = Base64.encode(USERINFO.token + ‘|‘ + moment().utc().format(‘YYY-MM-DD HH:mm:ss‘ + ‘|‘ + JSON.stringify(config.data)));
      config.data.hospitalId = USERINFO.hospitalId;
    }
    let TOKENSTART = token.slice(0,10),
        TOKENEND = token.slice(10);
    token = TOKENEND + TOKENSTART;
    config.headers[‘token‘] = token;
  }
  return config;
}, err => {
  tryHideFullScreenLoading();
  Message.error({ message: ‘请求超时!‘ });
  return Promise.resolve(err);
})
// 响应拦截
axios.interceptors.response.use(res => {
  tryHideFullScreenLoading();
  switch(res.data.code) {
    case 200:
    return res.data.result;
    case 401:
    router.push(‘/login‘);
    VueCookies.remove(‘userinfo‘);
    return Promise.reject(res);
    case 201:
    Message.error({ message: res.data.msg });
    return Promise.reject(res);
    default :
    return Promise.reject(res);
  }
}, err => {
  tryHideFullScreenLoading();
  if(!err.response.status) {
    return false;
  }
  switch(err.response.status) {
    case 504:
    Message.error({ message: ‘服务器被吃了⊙﹏⊙∥‘ });
    break;
    case 404:
    Message.error({ message: ‘服务器被吃了⊙﹏⊙∥‘ });
    break;
    case 403:
    Message.error({ message: ‘权限不足,请联系管理员!‘ });
    break;
    default:
    return Promise.reject(err);
  }
})
axios.defaults.timeout = 300000;// 请求超时5fen
// RequestBody export const postJsonRequest = (url, params) => { return axios({ method: ‘post‘, url: url, data: params, headers: { ‘Content-Type‘: ‘application/json‘, }, }); }
// formData export const postRequest
= (url, params) => { return axios({ method: ‘post‘, url: url, data: params, transformRequest: [function (data) { let ret = ‘‘ for (let it in data) { ret += encodeURIComponent(it) + ‘=‘ + encodeURIComponent(data[it]) + ‘&‘ } return ret }], headers: { ‘Content-Type‘: ‘application/x-www-form-urlencoded‘ } }); } export const getRequest = (url, data = ‘‘) => { return axios({ method: ‘get‘, params: data, url: url, }); }
Get请求的话是不需要进行设置的,因为get请求回默认将参数放在params中,post请求的话会有两个,所以我们这里讲post请求封装了两份。其他的东西的话大家不需要查看。
由于笔者近期较忙,所以,随便抽了一下,日后整理将会更新
